Amaphorti amaningi abuyisa izinkampani ezinzima kodwa zihlela isikhundla sokuhlelwa kwe-hernia. Abasemthethweni bakhetha ngokuvamile inkulu encincane iyasebenza ngokuphelele nezinkampani zonke ezenziwa—sikhumbula amaporti e-10–12 mm kupha uma kufanele ngokweminyaka.

Ukubona kwe-BMI, ubukhulu bekugqibela kwesikhumba, nokuhlelwa kwezindawo zomkhakha

Ukubona kwebhodi yomuntu uyaphatha ngqo ubude obuhle bokugqibela. Amakugqibela okusebenzisa ubude obuhle (100–110 mm) ayisiza ngokuphelele ekufinyeza kumkhakha wokugqibela kubantu abanemilingo yomkhakha ≥ 30 kg/m² ngoba kunezihlangothi eziningi zokugqibela nezihlangothi zokuzimela. Kule ndawo, amakugqibela okusebenzisa ubude obungaphezu kwe-150 mm ayizofundisa ukufinyeza ngokuphelele nokuthula. Ukuchaza kwezindawo zomkhakha kuyabeka isikhungo esinamandla:

• Kubantu abanemilingo yomkhakha, ukufinyeza amakugqibela ngokuphambili—futhi ukubeka kusuka emva kwezihlangothi zokuzimela—kunciphisa ubude obuhle bokugqibela.
• Ukwenza incishisi yomgqashi enkulu kancane (isibonelo, 12 mm kumakugqibela we-10 mm) kunciphisa ukuthwasa, ukuthwasa kwesikhumba, nokuthwasa kwezinhlobo zokuvimbela.
• Kubantu abanemilingo emnye, amakugqibela amancane noma ukufinyeza ngokuphambili kunciphisa ukuthwasa kwezinhlobo zokuzimela zokufinyeza ngokungafanele.

Ukufanana kwezilinganiso kusobala kubiza ukufinyelela kwe-peritoneum yonke, kungakhathali ukuvula kwe-CO₂, nokuhlela ukuphakanyiswa kwe-pneumoperitoneum—okuyisisekelo esikhulu ngaphandle kwe-trocars eziyisithembu zokusebenza ngokushesha.

Ukuqonda Ukuthi I-Tip Design Yezinkulungwane Zokusebenza Ngokushesha Zokulapa Kuyisafeti

Umsinga wokuphepha kwe-trocar yokuqala yase-laparoscopic yasezinkulungwane zokusebenza ngokushesha uyaphinda ku- tip. Izindlela zokusebenza ezintsha—ezingasolwa ngokudilayatha, ezibonisa izinto ngokukhona, nezibonisa izinto ngokugcina—zizoba ngamanye amandla okunyelela emkhawini yokugcina ukuthi kuzoba ngezinkinga zokugcina izinto zemkhawini ngokusebenza kwe-biomechanical.

Izindlela Ezisolwa Ngokungasolwa, Ezibonisa Izinto Ngokukhona, Nezibonisa Izinto Ngokugcina: Iziphakade Zokugcina Izinkinga Zokugcina Izinto Zemkhawini

Amathuba okukhuluma ngaphandle kokuchitha amasiko ayisibonelo esikhundleni sokuchitha, kubeka ukuthi kungabi nesiphakade sokuchitha kwezinhlobo zemithambo yezinye izindawo—kuyinto eyenkulu ekuphambaneni nezinhlobo zezincwadi ezinomthwalo wokuchitha ngokungazi. Amatrocars okubona akhuluma ngokubona kwesibonelo esihlanu esikhiqizwa kusuka emseleni wokufaka, kubonisa amasiko asefascia ngokushesha; izidata zokuhlanganisa izifundo zokufunda kubonisa ukuthi lokhu kunciphisa isiphakade sokuchitha kwezinye izindawo ku-0.1%. Amachitha okugcinwa akhuluma ngokugcinwa kwezincwadi zokuvalela okuzihlukanayo okuzihlukanayo kuzokufika kwezinye izindawo, kubeka ubucinane bokugcinwa ngokungazi kwezincwadi zokuvalela.

Ngoba amatrocars okusebenzisa kuphela kanye ayisebenzisa kabusha, bayabagcina ubucinane bakwesibonelo sokuchitha nokugcinwa kwezinkambo—ngaphandle kwezinhlobo zokusebenzisa kabusha, apho ukuchitha kwezincwadi kunciphisa ubucinane bakwesibonelo sokuchitha ngokuphakama kwe-40%. Lokhu kubeka ubucinane bakwesibonelo sokuchitha kubaluleke kakhulu kusukela kwezinye izindawo kanye nokubaluleka kwezinye izindawo zokugcinwa kwezinye izindawo.

Ukubeka ubucinane bakwesibonelo sokuchitha nokubeka ubucinane bakwesibonelo sokuchitha kwezinye izindawo ngamatrocars okusebenzisa kuphela kanye okwesilaparoskopu

Ukuchitha kwezinkambo, izindlela zokuchitha kwe-CO₂, nokubaluleka kwezinhlobo zokuchitha kwezinye izindawo zokuchitha kwezinye izindawo

Ukuphatha kwe-pneumoperitoneum kubhekisele kwezinhlangano zemivali ezinamandla nezilungile. Amatrocars okusebenzisa ngokushesha amathuba amaningi akhiwa ngokuthi abe nesikhumba sokugcina esihlanu noma isikhumba sokugcina esiphakathi—kodwa kusobala ukuthi kubhekisele kwezikhumba zokugcina zokuphatha okwesibini—okuzokufaka ngokuphelele emitholeni yezinkampani ezingama-5 kuze kube ma-12 mm. Ukuzimela kwezinkampani kubonisa ukuthi izindawo ezihle zisobala ukuthi zizokugcina i-CO₂ ngaphansi kuka-0.5 L/min ngaphansi kwemiphumela ya-15 mmHg—lokhu kukhona kakhulu ekliniki futhi kusobala ukuthi kuyabulawa ukubona nokugcina i-gas.

Amaphutha amahle okukhanya akhanyisa ukuthi angavaliwe ngokuphindeleka kwezinkambo zokusebenza, ngakho-ke amaphutha okugcina amakhubona ayisinye ayasebenza ngokungafanele ngokungabi nesikhundla esingaphansi nokuguqula kwezinkinga zokushaya. Ngokusebenza kwezinkambo zokufaka umoya (≥40 L/min), lezi zivali ziyakhathazisa ubunzima bokwenzela umoya ngokungafanele ngokungabi nesikhundla esingaphansi kwe-2 mmHg—kukhuluma ukuthi akusizi ukuthi umoya udlule ngokuphindeleka okuyithintela ubukhulu bokwenza izindlela zokusebenza. Umhlango we-2024 wabonakalisa ukuthi lezi zivali zokugcina ngokuphindeleka zizihlala ukuvalela umoya ngokungafanele ngokuphindeleka ngokungabi nesikhundla esingaphansi kwe-78% ngokulingana nezivali zokugcina ngokuphindeleka, okuhlanganisa ukuthi izindlela zokusebenza ziyasebenza ngokuphindeleka.
